code_loader.leap_binder.set_ground_truth

The leap_binder.set_metadata binding function points to Metadata Function. In addition, it defines the metadata_type and name for reference.

code_loader.leap_binder.set_metadata(
    function=MetadataSectionCallableInterface,
    metadata_type=DatasetMetadataType,
    name=str
)

Args
function	(MetadataSectionCallableInterface) This parameter points to the Metadata Function mentioned above.
metadata_type	(DatasetMetadataType) This property helps visualize the metadata data. For a float ground truth, use DatasetMetadataType.float For a string ground truth, use DatasetMetadataType.string For a int ground truth, use DatasetMetadataType.int For a boolean ground truth, use DatasetMetadataType.boolean
name	(str) with the given name of the input, e.g. image.
